While there is no cure for
allergies, treatment may
involve eliminating contact with the offending allergen (a diet change, for example, if the
allergy is to a
food substance), treating to relieve itching and other symptoms, and
allergy testing and injections.
This
involves taking a detailed history of symptoms, a complete physical examination and some preliminary laboratory
tests to rule out other reasons for itching / hair loss (namely mange, ringworm,
food allergy, hypothyroidism).
